Wow, I absolutely love the detail you put into her hair!! Well done!! I think one of the most helpful things I learned in art class in highschool was facial proportions. A face should be about 5 eye-widths wide. There should be an eye-width space between the two eyes, and then an eye-width space on either side of each eye (between the outside edge of the eye and the edge of the face). I think scaling down the size of the eyes might be helpful in making this picture look more realistic. I hope I explained this well enough to be helpful to you! Keep up the great work!!
